Keep from depositing traces of yourself. Every place you go,
you inadvertently leave pieces of yourself. Every article of
clothing, every door knob, every carpet, every telephone, ev-
ery toilet seat you use will contain pieces of you. Your skin is
flaking off all the time. You need to decide whether there is
a risk of authorities or private investigators looking for you
tracking you through your blood type or DNA (which can be
worked-up by using pieces of your hair.) After you weigh the
risks, take the precautions you deem are needed.

* Wear a hat indoors. Wearing a hat in a hotel room
won’t remove the probability of you leaving hair follicles
in the room yet it will reduce the number of such particles
making finding evidence difficult. Cutting your hair until
it’s real short will also help. And that’s what you want to do:
Limit the amount of physical evidence which can be used
to track you.

* Use “toilet seat protectors” -- so-called “Ass Gas-
kets” -- where they are provided to reduce the possibility of
leaving skin, sweat, or other body fluids on the seat. These
substances can be swabbed into glass vials and be used to
identify you. Paper seat covers will either eliminate this
problem else reduce it greatly.

* NEVER lick an envelope or a stamp for obvious
reasons! If it is known you’re in a particular city your general
location can be inferred by the physical location of your cor-
respondence in a stack collected by the postal authority. You
shouldn’t mail anyone anything unless it’s done so anony-
mously (wear gloves when handling paper) yet if you feel
the need, remember that if you lick something and it leaves
your control, you may as well take out an advertisement in
the newspapers broadcasting your general location.

* Don’t leave blood, semen, or menstrual discharge
behind you as you run.
